Seems to me, that I did an article about Quirts and their use - but I don't remember if it was for CAS City.
In general - use of the Quirt had heavy Mexican influence, as did much of the trappings of the American Cowboy.
He adopted much of the gear that originated with the Vaqueros - and you saw it being used in the Southwest.
Up North - slightly different gear was more prevalent, and they don't seem to show in period photos.
Many highly-decorative quirts came out of the different prison systems and were inmate-made.
Vaya,
Scouts Out!
